(c1. 1x1-49) vention consists inA certain constructionsandy combinations hereinafter fully described and then specifically setforth in the-claims hereunto appended.. n j

Heretofore safety `devices on cigar machines Were arranged so that onlythe cutter A,rollers- Would be stopped when an obstruction was on thewrapper die, `While the rest of .the machine con- ,tinued its movements.The` advantage of the present deviceisthat in case of an obstruction on`the Wrapper die the. Whole machine comes to a stop and no bunches inpreparation willzbe lost.

In the accompanying vdrawing which vvforms a part Vof'this specificationand in which like characters of reference indicated the same or likeparts:

Fig. 1 is a plan View, showing the improved cutter roller and safetydevice arrangement; and

Fig. 2 is an enlarged view of a portion of Fig. 1, showing the actuatingparts of the device.

In carrying the invention into effect there is provided a drive shaft, aclutch device for driving the shaft, a cutting bed, means driven fromthe shaft and cooperating with the cutting bed to cut a wrapper from aWrapper leaf on the bed,

mechanism actuated by an obstruction on the cutting bed to disengage theclutch, and vautomatic means for locking the clutch device in disengagedposition. In the best forms of construction contemplated the clutchdevice includes a driven pulley looselyv mounted on the drive shaft, aclutch member splined on the drive shaft and engaging the pulley, and ayoke engaging said clutch member and adapted to shift it out ofengagementwith the pulley, and the locking means includes aspring-tensioned lever adapted to retain the yoke in shifted position.In the preferred form of construction the cutting means includes apivoted cutting arm arranged to swing over the cutting bed and actuatedfrom the drive shaft to swing about its pivot over the cutting bed, andsaid mechanism includes a safety arm pivoted on the cutting arm, a stopbracket loosely mounted on the pivot of the cutting arm and connected tothe clutch device, and a Wedge on the safety arm adapted to clamp thesafety arm to the stop bracket, when the motion of the safety arm isobstructed-thereby disengaging the clutch'.

claimsy for the particular device selected to illustrate the inventionis but one of many possible concrete embodiments ofthe same. The inven-,jy

tion, therefore, is notto be restricted to the specific constructionshownand described.

` Ina cigar machinathe Wrapper leaf is spread by an operator on acutting bed where the leaf is held by suction. The, cuttingbed usedl'inthe present embodiment fof. the invention'is' of usual {construct-,itinand consists'of af'suction shell 5,7`a Wrapper cutting die 6 and awrapper head 7. A

cutting arm 8,.also of. usual construction, and carrying afpair` ofcutting -rollerslfv9 thenpasses over the die 6`a`nd cuts a leafsec'tionfrom the leaf, whereupon the cutting arm returns the cutting rollers 9to inoperative position. The leaf sectionl removed lfrom vthe'vvrapp'erhead 7 by means ofma wrapper carrier (not'shovvnLfand applied either asa binder in the formation of a cigar bunch, or as a Wrapper intheformation of aA cigar from a cigar bunch. The cutter arm 8 is pivotedon a stud l0 and is equipped with a lever ll-connected through a link 12to a bell crank lever r13 pivoted to stud 14 which is held by a bearingbracket 15. Bell crank lever 13 by means of link 16 is actuated from acam lever 17 carrying a cam roller 18 engaging in a cam track 19 of cam20 mounted on shaft 21. Cam lever 17 is pivoted to a stud 22 supportedby bracket 15. Shaft 21 is driven by means of a bevel gear 23 meshingWith a vbevel gear 24 mounted on shaft 25 which carries a slidablefriction clutch 26 splined thereon and engaging with a pulley 27 looselymounted on shaft 25 and driven by means of belt 28 from the main driveof the machine. Cutting arm 8 which is oscillated by means of cam 20carries a safety arm 29 pivoted to stud 30. To safety arm 29 is fastenedan eccentric Wedge 31 which by movement of the arm 29 in the directionof the arroW,.Fig. 2, Will engage With the clamping surface 32 of stopbracket 33, thereby causing motion of the latter which is pivoted onstud in the same forward direction as arm 8. Stop bracket 33 islequipped with a lever 34 engaging with a yoke 35 operating the frictionclutch 26. The yoke 35 is pivoted to a stud 36 fastenedto the main frameof the machine. A tension spring 37 causes arm .29 to rest against stopstud 38, assuring a clear- .ance between Wedge 31 and clamping surface32 vThesevariousmeans and parts may rbefvvidely varied-iniconstructionWithin thescope of the the disengagement of friction clutch 26 andthereby stopping the machine. In order to prevent spring 39 fromengaging clutch 26 before the trouble in the machine is corrected, alock lever 40 is provided which by means of a light tension spring 4lpulling the lock lever against the stop pin 45, follows the movement ofyoke 35 When disengaging clutch 26, thereby .keeping yoke 35 fromretreating and assuring that the clutch remains in disengagement untilthe trouble in the machine is corrected. Lock lever 40 is provided witha hand lever 42 and pivo'ted on a stud 43 mounted in the main frame ofthe machine. fected by operating hand lever y42 in such a manner as torelease lock lever 40 from lever 35, whereupon spring 39 seated againstcollar 44 mounted on shaft 25 actuates and engages clutch 26 again.

What is claimed is:

1. The combination with the drive shaft of a cigar machine, of a Vclutchdevice for driving said shaft, a cutting bed, means driven from saidshaft and cooperating with said cutting bed to cut a leaf-section from aWrapper leaf on said bed, mechanism actuated by an obstruction on thecutting bed to disengage said clutch device, and automatic means forlocking the vclutch device in disengaged position.

2. The combination with the drive shaft of a cigar machine, of a clutchdevice for driving said shaft, a cutting bed, means driven from saidshaft and cooperating with said cutting bed to cut Aa leaf section fromya Wrapper leaf on lsaid bed, mechanism actuated by an obstruction vonthe cutting bed to'disengage said clutch device, and automatic means forlocking the clutch device in disengaged position, said clutch deviceincludn ing a driven pulley loosely mounted on the drive shaft, aspring-pressed clutch member splined The re-starting lof the machine isef-` on the drive shaft and engaging said pulley, and a yoke engagingsaid clutch member and adapted to shift it out of engagement With saidpulley, and said locking means including a spring-tensioned lock leveradapted to retain the yoke in shifted position.

3. The combination with the drive shaft of a cigar machine, of a clutchdevice for driving said shaft, a cutting bed, means driven from saidshaft and cooperating With said cutting bed to cut a leaf-section from awrapper leaf on said bed, mechanism actuated by an obstruction on thecutting bed to disengage said clutch device, and automatic means forlocking the clutch device n disengaged position, said cutting meansincluding .acam geared tosaid drive shaft, a cam lever operated by` saidcam, a cutting arm connected to said cam lever, and cutting rollers onsaid arm arranged to engage the tobacco leaf on the cutting bed.

4. The combination with the drive shaft of a cigar machine, of Ia clutch`device for driving said shaft, a cutting bed, means driven from saidshaft and cooperating with said cutting bed to 4cut a leaf-section froma `Wrapper 'leaf on said bed,`
